Whitetip reef sharks rest in stacks under the pinnacle's overhangs during the day, packed into crevices with their heads pointing outward in the characteristic resting posture that gave this species its reputation as the 'lazy' reef shark. After dusk they become the dominant nocturnal predator on the reef, using their slender bodies to pursue fish into coral crevices that larger sharks cannot access. Daytime divers routinely find three to eight resting whitetips at depth on the pinnacle's shaded northern face.
